Specification of Letters Patent. Patented June 27, 19] l Applicationfiled September 4, 1809. Serial No. 516,301.

To all whom it may concern:

Be it known that I, \Vmnmn SUMNER, a subject of the King of GreatBritain, and resident. of Liverpool, England, have invented certainImprovenuants in Cash-Registers, of which the following is aspecification.

The present invention relates to certain improvements in cash registers,and comprises certain devices for setting the mechanism in position tomake the desired record; by means of levers or handles, means forcommunicating the motions of such setting devices to the printing wheelsand totalizers, means for exhibiting tablets'for indicating to thecashier and customer the amount f the sale recorded, means forcontrolling the till, and means for causing the several devices abovereferred to, to cooperate with one another.

Referring to the drawings; Figure 1 is a front: elevation of themachine, showin" the setting handles and drums, portions the casingbeing removed. Fig. 2 is a front elovatim. showing the operatinglever-frame, portions of the casing and of the mechanism being removed.Fig. 3 is a sectional end view, showing the schcn'ie of chains by whichthe motions of the setting drums and the operating lcvcr-fran1e aretransmitted to the several devices of the machine. Fig. 4 is a rearelevation of the machine. Fig. 5 is at sectional end view, showing thepaper record printing device, and Fig. (3 is a plan of this device. Fig.7 is a sectional end view, showiug the setting drum locking device, thetill locking device. and. device for fccdin forward the totalizcr. Fig.8 is an end view of the machine, showing a check action for controllingthe movements of the operating lever. Fig. 2) is ascctional detail ofthe totalizcr train. l ig. '10 is a front view of tliiijadvcrtisingmechanism employed on the nnchinc, Fig. 11 an end view, Flglfl 12 a fl.(it view, of the outer casing of the niachii'ie. Fig. 13 is an end viewand Figfill a rear view of the casing.

The setting devices comprise two drums, 1. can-h rcm'csenting differentdenominationsot' Milli, such as pence and shillings. To these drums arecoupled the lpvers 2. projecting through slots in the machine casing.the setting being ctlertcd by moving these lovers in their slots.Suchmovcmcnt of the setting drums is conununit-atcd or is permitted tobe communicated to the several devices of the machine by means ofchains, as hereinafter described. After the several devices of themachine have been set to afford a record, the operation is completed bywhat may he termed the operatmg lever, 3, as will be doscribed. Thedrums 1 arefixed on sleeves 4-. Also fixed on the sleeves 4 are pulleys5, 13.

From these drums and pulleys chains are led to the several devices ofthe machine. The operating lever 3 is attached to the rocking shaft 7.Fast on shaft 7 are cranks 8. From the ends of cranks 8 the frame-bars 9load to bar 10, the ends of the latter traveling in slots 11 in the endplates 12.

The paper record mechanism is a scparable unit, comprising the plate 13carrying the paper spools 14. The plate 13 is attached to the pillar 15on. sleeve 16 by the catch. 17, and is supported by the trunnion 18 onthe bearer bar 19, one end of this bar being attached to sleeve 16 whileits other cud rests upon the cross-piece 20 of the frame-bars 9. Thetrunnion 18 is located under the sockebpiece 21 on the bar.19. Byundoing the catch 17 the paper record device may be removed as a whole,through the door 136, for examination and removal of the printed record.The impression of the printing-wheels 22 is taken by the paper strip :23at each depression of the 0 rating lever '3, the platen 24 being fixe tothe plate 13. The bearer-bar 19 follows the downward movement of thecross-piece 20 until the paper and platen rest upon the printing wheels,the impression being made )y the terminal downward motion of thecross-piece 20 heingcommunicated to the bar 1!) by the spring 25. As thepaper record device rises again, its ratchet wheel 26cmages the pawl 27so that the paper strip 23 is fed forward tor the next record. Thewheels 22 are inked by rollers 28 carried on the rocker 29, which latteris linked to an arm 30 on sleeve 16. The printing wheels arerespectively carried on two sleeves 31. which also carry pulleys 32.From the pulto s 32 chains 38 lead to the drums 1, to which they areattached, and thence to the pulleys 34 of the totalizer. The printingwheels are returned to zero by chains 35 and springs 36 attached topulleys 6.

The numeral disks 37 for indicating through apertures 38, the, positionin 'which the drums 1 are set, are rotated by chains 39 attached toalleys 6, springs 40 serving to return the he 37 to zero.

The totalizer comprises four numeral disks, 41, 42, 43, 44, representingpence, shillings, pounds, and increments of twenty pounds, respectively.The disks 41, 42 rotate ull spindle 45, the disks 43, 44 rotating on thehollow shaft 46 carried in bracket 47 which is fixed to the sta rods 47.The pawl arms 48 which turn t 1e pence and shilings' disks are carriedon sleeves 49, on which the pulleys 34 are fixed. The pins 51 of thepawls 52 are normally out of gear with the lesser ring of teeth on thedisks 41, 42, so that after the pulleys 34 are turned by the sleeves 49and chains 134, the pawls and pins 51 move freely backward over saidteeth. Said pins are brought into gear with the teeth of the disks bythe links 53 connecting such pawls with sleeves 54. From sleeves 54 theslack chains 55 lead to nipples 56 on cross-piece 20.

In operation, when the drums 1 are set as required, the chains 134 andsprin s 135 rotate the sleeves 4t), and the paw arms 48 travel. backwardover the teeth of the disks 41, 42 each to the required tooth. In thisaction the arms 48 have-by the links 53- also turned the sleeves 54, sothat the latter have each wound up a portion of the slack chains 55. Theoperating lever 3 is then dopressed, the cross-piece 20 descends, thechains 55 tighten and then turn the sleeves 54, until the amount ofslack chain wound thereon is unwound,-and in so turning the sleeves 54the links 53 draw the pins of the pawls 52 into gear with the teeth ofthe disks 41, 42. The pawl-arms 48 are thus, during the downwardmovement of the lever 3, turned forward the same distance which theywere turned backward by the drums 1, and in this forward n'iovemrnt ofthe pawl arms they carry with them the disks 41, 42, and so add theamount to the total sn'm.

The carrying forward of a shilling from the pence disk tl. to theshillings disk 4-2 il effected by the trip lever 57 on the loose sleeve58. pawl 59 on (his lover gears with the larger ring of teeth on disk42. the other end, (it), of the lever, being connected by a spring (51with the bar U2." The lever end 60 is also engaged by the detent (33,which is influenced by sprii'ig 11;") attached to sleeve 116. At eachrevolution of disk 41 a projection (54 thereon presses the detent. Gilon of contact with the lever 57, allowing the latter to be canted to thestop piece 50 byits spring 61, so that its pawl 55) is drawn backwardover one tooth on the disk 42. As the lever 3 rises, a strut (if) onbearer-bar it) raises the lever 57, so that the latter rotates the disk'42 one tooth and also retingages itself with the detent 63. At. eachrevolution of the disk 42, the disk 43 is fed forward. one tooth by aprojection or, on the disk 42 an aging a tap'pet rod 67 on the sleeve(58. A so on the sleeve 68 which is seated on the shaft. (38 is thepawlarm 69 gearin with the teeth of the disk 43, a s ring 70 e ectingthe forward movement 0 such pawl-arm. (1on1 lete revolutions of the disk43 are trans nitted to the disk 44 by the tappet 71, pawharm 72 andspring 73,

113 are non-return pawls, and the disks are caused to recoil thereto bythe bent springs 114.

The totalizcr may be read 0H through the doorway 137.

The tablets 74 by which the amount of the sale is exhibited through aertures 75, are as follows. The ence tab ets are twentythree in number,caring numerals indicating from id. to 114d. while the shillings tabletsare twenty in number. These tablets are pivoted on pins 76 and rest uponpins 77. The tablets are canted upward into their. visible osition asfollows. From the pulleys 5, c wins 78 pass to blocks 79 which slideupon pins 80 carried in the bar 62, that is the blocks are drawn forwardby the chains 7 8 against the springs 81. Above the blocks 7%) aresimilar .blocks 82 sliding on square rods 83 in the upper ends of theframe-bars 84. The bars 84 are slotted and possess vertical movementupon the pins 80, 85, this vertical movement being due to the rise andfall of the bar 10, the set-pins 86 in the ad j ustabl'e ends 87 of thebars 84 resting on the bar 10. The blocks 79 are connected to the blocks82 by springs 88. Fork-pins 80 rise from the blocks 79 to limit thetravel of the blocks 82. The blocks 82 carry lifter 100 arms 90 by whichthe tablets are raised to their visible position, as follows. \Vhen theblocks 79 are drawn outward by the chains .78 a distance proportional tothe movement of the drums 1, the blocks 82 cannot immediately follow,because their lifter arms 90 are behind the rearmost tablet or are betaeen two tablets, aecordingl as they were last left. Consequently theplus 83 carrying the blocks 82 must be lowered to allow the lifter arms90 toescape from and )ass bencath the tablets, and this is efiecte bythe depression of the lever 3, allowing the bars 84. to fall and carrywith them the rods 83 and blocks 82. The blocks 82 then follow theblocks 7!) until arrested by the forks 89 of the blocks 79, when thelifter arms 90 will be inonediatcly under the specific tablets whichindicate 'the sum to be recorded. \Vhen the lever B rises, the bars 84are raised by the bar 10, carrying with them the rods 83 and blocks 82,so thatthe lifter arms 90 raise the tablets and hold them against theabutment bar 91 until the next depression oi lever 3. The lifter arms 90are elastic and keep the tablets against. the bar 91, this clasticityserving-when the blocks 82 are lowcred-to tip the tablets so that theyfall by gravity into their horizontal positron.

To lock the drums 1 in theirset ipdsitions, 139

their sleeves 4 move lengthwise on the spindles 92. '1 0 afford thismovement the levers 2 are tulcrumed on the spindles 92 and coupled tothe drums 1 by studs 93. A sto piece 94 abuts against the bar 97. Eacdrum 1 possesses perforations 95 corresponding in number with thesetting motions of the drums. When the drums are moved sidewise thedetents 96 on the bar 97 enter these perforations, and the drums areheld in this locked position by the inclined bars 98namely as the leverdescends the, bars 98 push the drums sidewise so that one of theirrespective perforations 95 engages in the detents 96. These bars 98 aresecured to bars 9 and are carried downward by the cranks 8 by means ofthe lever 51; and the sleeves 4 being \slidable on shafts 92, are].)res-'ed into normal position relative to said shafts by means of saidbars 98, by which means'said drums are secured in engagement with thedetents 96 when the lever 3 is de- 'u-essed; the normal position of thearms being retained by springs 90. The drums 1 may be unlocked from thedetents by moving lever 3 laterally when the lever 3 is raised,whereupon the drums return to zero and to their normal position of theshaft 92, by means of the springs 99, attached to pulleys t]. The drumsare adapted to be unlocked, by the cams 100 on the shaft 101, when thecash drawer is withdrawn, by contact of said cams with the outer flangeof the drum. p, On the shaft 101 is the arm 102, against which the backof the drawer 103 abuts, the shaft 101 being turned by springs 10% whichconnect the arm 105 with the bar 106. W'lzen the drawer is closed thecams 100 are clear of the drums 1, allowing free movementof the latterlengthwise of the shaft 92, when the drawer is withdrawn the cams 100engage the drums tomove them in the direction of their axes and retainthem against rotation until the drawer is closed. The drums 1 cannottherefore return to zero while the drawer is open or while the lever isdepressed.

The bars 9 and'98,the cross piece 20, and the bar 10 constitute theoperating frame. which is actuated vertically by the lever 3,

through the.1nedium" l5f the shaft 7 and cranks 8.

The cash drawer 103 is released by the descent of the bar 10, the latterstriking the end of detent lever 107 fnlcrumed on the bar 106, the otherend of this lever engaging striking plates 108 on the drawer 103.

To insure complete downward and lipward. movementsof the lever 3, whenonce initiated, a spindle 109 is pivoted on the. and of bar 10, andpasses through a eylin drical aperture in the end of check-lever 110,the other end of this lever being controlled by the bow-spriru 111. Thelever 1.10 is tippedfinto eitheco? the two positions shown, by the stoppieces 112 on the spindle 109'. The effect is, that the angle of thecheck-lever relatively to, the axis of the spindle 109 determineswhether the latter passes freely through the vlindrieal aperture in thecheck-lever or is gripped thereby. The recovery or upward movement ofthe lever 3 is assisted by thespring 138.

An advertising device is moved at each operation of the lever handle 3,as follows. The advertisements are set forth on a sheet of linen or thelike, 117, arranged to wind on and off rollers 118, 110 jourrialcd inthe plate 120. The advertisements are exhibited through the window 121in the back of the reister case. The roller 11% is a spring ro ler ofthe usual type, and the roller 119 is rotated step by step by the pawl122 which gears the ratchet 123 and is carried on the pawl arm 124, thelatter lieing coupled by a chain 125 with the crank 126 on one end ofthe shaft 7. The sheet 117 is wound up on the spring roller 118 and isdrawn therefrom by the roller 119, and when the sheet has been wound onthe roller 119 the latter is released-as hereinafter described-so thatthe sheet is again woun on to the spring roller 118, and the stepby stepunwinding motion again commenced." A detent pawl 127 is frictioi'iallymounted on its pivot, so that it will remain in whichever position it isplaced in. This detent 127 is pressed into engagement with the ratchet123 at each movement of the lever 124 by the spring 128. on the latter,and is pressed out of engagement by the rotation of the ratchet. Inorder that the detent 127 may he held clear of the ratchet, to allowofthe sheet 117 being wound back upon the spring roller 118. a. pinion129 upon the said ratchet gears with a messenger wheel 131), and fixedin this wheel is a pin 131, which, when the sheet is -wound upon .theroller 11 8, engages the detent 127 and holds it away from the ratchet.As the pawl aim 12-1 has now returned to its position of rest, itsspiking 128 no longer presses upon the detent 127, so that the roller118, pinion 129 and messenger wheel 130 are ..free to recoil while thes" ring roller 118 is winding up the sheet 11 i \Vhen the sheet 117 isre-wound on the richer 118, a pawl 132 drops into a. notch 133 in theroller 11!) ,1 which has been uncoverediby the unwindin sheet, and soserves as a limit to the rewin in of the sheet on the roller 118.
